reflux column

基本解释

In many cases, a rectifying column with reflux is used to improve the performance of the batch still.
在许多情况下，用带有回流的精馏塔以改善间歇釜的分离性能。
The dynamic characteristic of concentration change on plates of batch rectification column in no reflux start up process and in no reflux period of pulse operation process have been calculated.
建立了间歇精馏无回流操作过程的数学模型，采用四阶龙格库塔法求解初值问题，计算无回流开工过程及间歇精馏脉动操作过程中无回流周期内各塔板浓度变化的动态特性。
Adding intermediate reflux and cooler and using packed column replaced plate column are suggested. The effect is evident in practice.
对总厂汽油分离塔提出增建中段外回流取热和将板式塔改为填料塔的建议，经实施后效果明显。
